Interesting to see which nation has the fastest thundercats...
some decent numbers from Aus and the states but several guys in SA claim 113kmph race pace, with a modified 50hp Yamaha!

I bet all of the 750 records are set by a 50D Tohatsu. 68 mph with a blueprinted motor is impressive and similar to the 66 mph in T750. Based on our T750 class here and the strong performance of the OMC motors I would think the OMC may? be able to break those records.
